HACKENSACK — Prosecutors have charged a 20-year-old Fort Lee man who authorities said was intoxicated when the car he was driving slammed into a building, killing one passenger and seriously injuring another in Ridgefield last month.

The driver, Tamer Ammar, remains hospitalized with injuries from the violent July 24 single-car wreck at the intersection of Broad Avenue and Edgewater Road, Bergen County Prosecutor John L. Molinelli said in a statement Saturday.

His front seat passenger, Miles Reme, 20, of Fort Lee, died at Hackensack University Medical Center about an hour after the 1:30 a.m. crash, authorities said. Another passenger, James Racanelli, 20, also of Fort Lee, was rushed to the hospital with serious injuries.

Ammar was driving a Honda Civic northbound in the right lane of Broad Avenue when he lost control, went onto the sidewalk and careened through two bus stop signs, according to Molinelli.

The prosecutor said Ammar continued off the sidewalk, across the roadway and went north in the southbound lanes before crossing a grass median and slamming head-on into an accountant’s office.

“The collision scene, from the bus stop sign posts to the building where the Honda came to rest, measured approximately 1,400 feet long,” Molinelli added.

The Prosecutor’s Office Fatal Accident Investigations Unit reconstructed the scene and learned Ammar was driving at “a high rate of speed,” before hitting the office, according to Molinelli.

“Investigators also developed information which indicated that Mr. Ammar was intoxicated, under the influence of controlled dangerous substances, at the time of the collision,” the prosecutor said.

Results were pending on a blood sample taken from Ammar the day of the crash, Molinelli added.

Ammar faces charges including death by auto, driving while intoxicated and assault by auto. Ridgefield Municipal Court Judge David Lafferty allowed Ammar to be released on his own recognizance while he remains hospitalized.
